COMBINATION-Tool..

SPECIFICATION forming part of Letters Patent No. 456,189, dated July 21, 1891.

Application filed Avril 8, 1891. seria No. 388.187. (No model.)

To @ZZ whom t may concern.-

Be it known that I, WILLIAM D. ARNoT, a citizen of the United States, residing at Athol, in the county of lVorcester and State of Massachusetts, have invented a new and useful Combination-Tool, of which the following is a specification.

My invention relates, chieliy, to improvements in combination-wrenches, although it may be used as ahainm er, pinchers, or vise, as the occasion may require.

The objects of lnyinventionare, first, to afford facilities forthe adj ustment of thewrench to a nut of any size more readily and firmly than has been attained heretofore; second,to provide the wrench with triangular lianges peculiarly adapted for use upon carriage-n uts; third, to provide a hand-vise that may be used as pinchers or tongs or as a wrench in places where other wrenches could not be operated to advantage, and, fourth, to provide a wrench that may be used as a hammer in the ordinary way. I attainthese objects in the manner illustrated in the accompanying drawings, in which- Figure lis a perspective View of entire combination-tool. Fig. 2 is aview in perspective K of square bolt and lower carriage and monkeywrench jaw.

Similar letters referto similar parts in each View.

The handles A A are connected at one end by means of a hinge-joint a, the other ends being rigidly attached to the wrench-heads B B. On the inner surface of the lower handle A is attached by means of a rivet a small piece of spring-steel o, so shaped as to press forcibly against .the upper handle A, thus forcing the heads B B apart,.when the thumbnut 0 is turned toward the upper end of the square bolt D, hereinafter described. The spring b is so slight that when the heads B B are open the jaws E E, F F, or G G may be adjusted to a nut of any size by pressing the handles A A together and turning the thumbnut C on the square bolt D, thereby providing a vise-pressure that prevents any objects held bythe jaws slipping therefrom until released bythe manipulation of the thumb-nut C on the square bolt D.

The right side of the heads B B are provided with horizontal flanges E E (see Fig. l)

to be used as monkey-wrench jaws. The loweriiange or jawEis movable, so that when the heads B B are spread or open it will attain its proper position directly opposite to and parallel with the upper jaw E, and keeping that position when the jaws are partially or wholly closed.

The left side of the heads B B are provided with triangular flanges F F, Fig. l, to be used as carriage-wrench j aws. The lower jawF is an extension of the bar forming the lower monkey-wrench jaw E, and is therefore adjustablein the same way. The jaws F F project far enough from the headsB B to assure their proper adjustment to carriage-nuts that do not project from the hub of the wheel.

When the carriage-jaws F F are adjusted iirmly to a nut by means of the thumb-nut C, the nut may be turned off and on the axletree with but one adjustment of the jaws F F, the pressure attained by means of the thumbnut C preventing the carriage-nut from leaving the jaws F F until the thumb-nut C is turned toward the upper end of the square bolt D, hereinafter described. j

Rigidly attached to the lower jaws E and F and extending upward through a square fcavity in the upper head B is a square bolt D, the corners of which are slightly rounded and have a heavy thread cut thereon.

The cavity in the upper head B is large enough to allow the easy passage of the upper head B over the smooth sides of the square bolt D. The bolt D,beingsq.uare, also allows the upper head B to move upon it without the additional play necessary if the bolt D was round and a heavy thread cut thereon. Again, the bolt D, being square, prevents the jaws E E and F F springing from their proper position when adjusted to a nut. A thumbnut C, the inner surface of whichis supplied with a heavy thread corresponding to that upon the square bolt D, is turned upon the square bolt D and provides the pressure pre- Aviously referred to.

On the under side of the loweradjustable jaws Eand F are two small projections c c, (see Fig. 2,) which move upon narrow flanges or tracks CZ CZ, placed ou each side of the lower head B, thus allowing the lower jaws E and IOO F to adjust themselves exactly opposite the upper jaws E and F, at the same time providing,r the connection between the square bolt D and the lower head B.

The heads B B terminate in vise-jaws or tongs G G, the inner surface of which are corrugated. These jaws or tongs will be used when the nut to be turned is in such a position that the jaws of the monkey-wrench E E cannot be adjusted properly. The j aws G G are adjusted to the nut and the handles A A turned, the motion given being` Ysimilar to that applied to a hand screw-driver in turnin g a screw.

The jaws G G may be used as tongs or pinchcrs,or, when the pressure afforded by the manipulation of thumb-nut C on the square bolt D is applied, may be used as a hand-vise in the ordinary way.

On the under side of the lower head B a hammer-head is placed to be used for driving bolts, tbc.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination, in a combinationwrcnch, of a carriage-wrench and monkeywreneh operated by means of a spring' l), handles A A, square bolt D, and thumb-nut C, substantially as described.

2. In a combination-wrench, handles A A, terminating in vise-jaws G G, operated by means of spring b, square bolt D, and thumbnut C, substantially as described.

The combination, in a combinationwrench, of a square bolt D with an adjustable jaw E and Rand a hammer-head H,wth the lower head B, all substantially as described,

TILLIAM D. ARNOT.
